Configure LLDP MED TLVs for Transmission on Ports

About this task

Use this procedure to configure organizational-specific TLVs for Link Layer Discovery Protocol (LLDP) Media Endpoint Devices (MED). LLDP MED TLVs are enabled by default.

1. Enter GigabitEthernet Interface Configuration mode:

   enable

   configure terminal

   interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

   

   Note

   If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

2. Disable LLDP MED TLVs for transmission:
   no lldp tx-tlv med {extendedPSE | inventory | location | med-capabilities | network-policy}
3. Restore LLDP MED TLVs for transmission to their default value:
   default lldp tx-tlv med {extendedPSE | inventory | location | med-capabilities | network-policy}
4. Verify the configuration:
   show lldp tx-tlv med

Example

Disable LLDP MED TLVs

Switch:1>enable
Switch:1#config
Configuring from terminal or network [terminal]? t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#interface gigabitethernet 1/2
Switch:1(config-if)#no lldp tx-tlv med inventory
Switch:1(config-if)#no lldp tx-tlv med location

Switch:1#show lldp tx-tlv med
